Journal ArticleDOI
Matter-wave interferometry in a double well on an atom chip
Thorsten Schumm,Thorsten Schumm,Sebastian Hofferberth,L. M. Andersson,S. Wildermuth,S. Groth,S. Groth,Israel Bar-Joseph,Jörg Schmiedmayer,Peter Krüger +9 more
TL;DR: In this paper, an integrated interferometer based on a simple coherent matter-wave beam splitter constructed on an atom chip is presented, where the authors demonstrate the splitting of Bose-Einstein condensates into two clouds separated by distances ranging from 3 to 80μm.
Journal ArticleDOI
Non-equilibrium coherence dynamics in one-dimensional bose gases
Sebastian Hofferberth,Sebastian Hofferberth,Igor Lesanovsky,B. Fischer,Thorsten Schumm,Jörg Schmiedmayer,Jörg Schmiedmayer +6 more
TL;DR: The experiments studying coherence dynamics show that 1D Bose gases are ideally suited for investigating one-dimensional systems, such as superconductors, quantum Hall systems, superfluid helium and spin systems.
Journal ArticleDOI
Probing quantum and thermal noise in an interacting many-body system
Sebastian Hofferberth,Sebastian Hofferberth,Sebastian Hofferberth,Igor Lesanovsky,Igor Lesanovsky,Thorsten Schumm,Adilet Imambekov,Adilet Imambekov,Vladimir Gritsev,Eugene Demler,Jörg Schmiedmayer,Jörg Schmiedmayer +11 more
TL;DR: In this paper, a complete experimental analysis of the shot-to-shot variations of interference-fringe contrast for pairs of independently created one-dimensional Bose condensates is provided.
Journal ArticleDOI
Integrated Mach–Zehnder interferometer for Bose–Einstein condensates
Tarik Berrada,S. van Frank,Robert Bücker,Thorsten Schumm,Jean-François Schaff,Jörg Schmiedmayer +5 more
TL;DR: A full Mach-Zehnder sequence with trapped Bose-Einstein condensates confined on an atom chip is demonstrated, highlighting the potential of entanglement as a resource for metrology and paving the way for integrated quantum-enhanced matter-wave sensors.
Journal ArticleDOI
Observations of Density Fluctuations in an Elongated Bose Gas: Ideal Gas and Quasicondensate Regimes
Jérôme Estève,Jérôme Estève,Jean-Baptiste Trebbia,Thorsten Schumm,Alain Aspect,Christoph I Westbrook,Isabelle Bouchoule +6 more
TL;DR: In situ measurements of density fluctuations in a quasi-one-dimensional 87Rb Bose gas at thermal equilibrium in an elongated harmonic trap observe an excess of fluctuations compared to the shot-noise level expected for uncorrelated atoms.
